The use of biological weapons has been recorded repeatedly in history. Unti
l recently, biological terrorism had been Little discussed or written about
. However, events over the past 12 to 18 months have made it clear that lik
ely perpetrators already envisage every possible scenario. Nations and diss
ident groups exist that have both the motivation and access to utilize biol
ogical weapons. In April 1994, a Russian biological weapons expert presente
d the conclusions of the Russian experts as to the agents most likely to be
used: smallpox, anthrax, and plague. Health care workers in the Kingdom of
Saudi Arabia (physicians, nurses, and emergency medical technicians) need
to be aware of the seriousness of the threat of biological weapons, and to
have an approach for the early identification, triage, and management of bi
ological weapons victims. Clues to the occurrence of a bioterrorism attack
include the abrupt onset of a large number of cases of a similar disease or
syndrome, the occurrence of diseases with unusual geographic or seasonal d
istribution, and epidemics of nonendemic diseases. Health care workers must
maintain a high index of suspicion, involve the hospital epidemiologist or
infectious diseases specialist, identify a clear administrative chain-of-c
ommand to minimize confusion, and rely on existing networks such as the hos
pital disaster-and-safety committee to ensure a multidisciplinary response.
Maximum readiness can be achieved by periodic readiness drills.
